What trucks have a 14-bolt axle?
Up until 1994, GM manufactured the 14-bolt in-house. Post 1994, the 14-bolt was built by American Axle &
Manufacturing. While the 14-bolt can still be found under many late-model GM 2500HD gas trucks and Suburbans, most ’01-and-newer ¾- and 1-ton diesel trucks use the AAM 1150 rear axle.
Is a 14-bolt semi-float good?
Still, the 14-bolt semi-float is a solid axle for a lot of applications. Compared to a GM 10-bolt axle (for example), a semi-float 14-bolt is a nice upgrade. You can spot a semi-float 14-bolt axle by counting the lugs (if it’s a six lug wheel, it’s a semi-float), or by looking at the wheel surface.
Are all 14-bolt axles the same?
Over the years, there have been millions of 14 bolt axles produced. And, of course, they weren’t all the same. GM 14 bolt axles were available in semi-float and full-float versions, and there are two types of hubs found on 14 bolt axles. Also, two different types of drums were used.

What does a full floating axle mean?
A full floating axle consists of a wheel hub assemble that is separate from the axle shaft. A spindle bolted to the axle tube supports the wheel hub by means of a pair of wheel bearings. Therefore, the weight of the vehicle and its cargo is transfered to the axle tube, rather than the axle shaft itself.
How do I know what axle ratio I have?
Method 1: Count the number of teeth on the ring gear and the pinion. Divide the number of the ring gear’s teeth by the number of the pinion’s teeth. This will give you the axle ratio.
What does a Dana 80 come in?
ID A Dana 80 Rear Axle in Chevy, Dodge Ram, or Ford Truck IDN-126. Was: Dana 80 Rear Axles have been in production since the 1988 Model Year. They have been used in Chevy/GMC 1992-2002 , Dodge(1994-2002), and Ford (1988-current) trucks vans, and motorhome chassis.
Is a 14 bolt rear end a Dana 60?
The 14 Bolt and Dana 70 axles are Heavier Than a Dana 60
The 14 bolt axle and the Dana 70 weigh more partly because they have 3.5″ axle tubes, which are slightly larger than the 3 3/8″ tubes found on many Dana 60s. This helps the tubes resist bending when side loaded by large tires.

The rear cover’s shape and the number of bolts are identifying features for GM rear differentials. The round 10-bolt cover with a bulge for the ring gear identifies this axle assembly as an 8.5-inch 10-bolt. The two lugs on the lower case at the 5 and 7 o’clock positions are also identifying features.
What is the difference between a full-floating and semi floating axle?
The axle shaft also rides on a large roller or ball bearing out at the end of the axle housing. For a full-floating system, the axle shaft only serves to transmit the rotational torque from the differential out to the wheel. It does not carry the weight of the vehicle as a semi-floater does.
What is a full-floating rear end?
In a full-floating axle, the axle is not attached to the axlehousing at all
it is allowed to “float” inside the axlehousing. A tubular shaft is mounted to the end of the housing and acts like your front spindle, only it is hollow to allow the axle to meet up with the wheel assembly.
What are corporate axles?
When the 14 bolt axle debuted in 1973, it had been developed under the “corporate” umbrella with GM providing standard design specs for all divisions. This made it a “corporate” axle rather than a division-specific axle. Thus, it became the “corporate” 14 bolt.

With the transmission in neutral, rotate the rear driveshaft by hand. Count the number of driveshaft revolutions required for one revolution of the tire. If the driveshaft turns approximately 3-1/2 times, you have a 3.54 ratio, etc.
Can you tell the gear ratio by the VIN number?
The gear ratio is usually listed in the VIN code located on driver’s door, the glove box, or the ID plate on the dashboard. Count the times a rear wheel goes around for one driveshaft turn: if its 3 1/2 it’s a 3.50:1. Divide the number of teeth on the ring gear by the number of teeth on the pinion gear.
What is the difference between SRW axle and a DRW axle?
